Want to change my ATF,,,,,synth or dino?????

[nuQ]

while doing my regular fluid checks, noticed the color of my ATF has gotten a little darker and should get another flush soon. my question is.....since i don't drive the Q a ton (and i think she's gettin' a little jealous of the new 325 is!!! LOL), is it really neccessary to use full synthetic (EXPENSIVE!!)????? i have the transmission cooler installed also. i think dennis uses valvoline regular ATF in his now but does regular flushes. if i keep a close eye on the color changes and flush accordingly,,,is there that much difference in using synth. vs. dino?????

The Mobil 1 ATF actually lowers transmission temperatures.

I dont know what the climate is like in Nazareth, but down here in the Lou I refuse to subject my weakling Q transmission to anything less than the best.

Since you drive so little you can do dino yearly.. youll be fine.....

Pretty cheap compared to transmissions.

Most BMW feel pretty small after I pass them. Especially the big ones.

like i said,,,,the bmw is fun but my Q is true love!!!!!! since i already have the trans cooler and drive about 5k miles or less a year was just wondering if dino fluid, changed yearly, would give the same protection as synth changed every 20-30k miles. i'm sure it would. or just tell by checking the color. if the color is still the same after a year with dino, have to assume the protection is still good.......
